I believe people do need some moral guidance. Not necessarily the 10 Commandments, specifically.
I mean, we see areas of the world, in our own country, where we've kind of let people do what they want to do and it ends with stealing and violence.
I think this is what a lot of people don't really get about religion and what we've lost as its become less in our society. Less common ground, less community interaction, less moral guidance... I don't see how anyone thought it would improve us by removing it and it hasn't.
